SPECIFICATION forming part of Letters Patent No. 642,582, dated February6, 1900.

Application iiled March 6, 1899. Serial No. 707,957. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM W. CHEESE- MAN, a citizen of .the UnitedStates, residing at Cincinnati, in the county of Hamilton and State ofOhio, have invented certain new and useful Improvements inCreasing-Machines; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art Ato which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specication.

This invention relates to certain improvements in creasing-machines,such as are especially adapted for use in creasing paperbox stock andsimilar materials; and the object of the invention is to provide amachine of this character of a simple and inexpensive nature which shallbe strong and compact in construction and shall be adapted for creasingthe stock sufficiently to permit the bending thereof to the proper anglewith the minimum weakening of the material at the crease.

The invention consists in certain novel features of the construction,combination, and arrangement of the several parts of the improvedcreasing-machine whereby. certain important advantages are attained andthe device is made simpler, cheaper, and otherwise better adapted foruse, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in theclaims.

In the accompanying drawings, which serve to illustrate the invention,Figure l is a side elevation of a machine embodying my invention, andFig. 2 is an enlarged fragmentary sectional view taken verticallythrough the machine in the plane indicated by line a a in Fig. 3 andshowing one set of the creasing mechanisms. Fig. 3 is an enlargedfragmentary face view showing the upper part of the machine with thecreasing mechanisms thereat, the central portions of the machine beingbroken out to save space. Fig. 4 is a view showing the rear face of oneof the adjustable carriers for the upper creasing devices, and Fig. 5 isa view showing the rear face of one of the slides whereon said carriersare held. Fig. 6 is a top edge View of the carrier shown in Fig. 4; Fig.7 is an end edge view of the slide shown in Fig. 5. Fig. 8 is afragmentary detail view showing one of the cutters employed for trimmingthe edges of the stock passed through the machine. Fig. 9 is an enlargeddetail sectional view showing one of the upper creasing devices.

In the Views, l l indicate the side frames or uprights of themachine-frame, these uprights being tied or braced together at the lowerpart of the frame by means of transverse tie-rods and being anged togive them the required strength.

2 indicates the feed-table at the front part of the machine forsupporting the stock to be fed into the machine, said table beingsecured at its rear part to lugs projecting forwardly from theframe-uprights l and being supported at its front part by a brace orbraces 3, extending down and connectedto the lower part of the frame.The machine is also provided with a delivery-table 4 for receiving thecreased stock, said table having at its rear edge an upright stop 5 tostraighten the edges of the sheets or blanks and having its forwardedges held to slide between spaced flanges 6 6, formed transversely onthe inner surfaces of the uprights l and adapted to receive the edge ofthe table 4 at each side of the frame between them, as shown in Fig. 3.The rear end of the delivery-table 4 is supported by means of links 7 7,one connected to the rear end of the table and the other to thelowerpart of the frame, the adjacent ends of the links being slotted, asshown at 8, to receive a bolt 9 or equivalent device for holding theends of the' links in adjusted position. By this construction it will beseen that the delivery-table 4 maybe made to extend more or. less farbehind the machine by releasing the bolt 9 and moving the slotted linksupon each other, the forward part of the table sliding between theflanges 6 of the frame, after which the bolt is tightened to hold thetable in adjusted position. In this way the table 4 may be adjusted toreceive against its stop 5 differently-sized blanks.

The uprights 1 of the frame are tied or con- IOO nected together attheir upper ends by means of a transverse guide-bar 10, extending acrossthe top of the machine to brace the frame and also serving as a guidewhereon the upper creasing devices are adapted for movement transverselyof the machine to permit of adjusting said devices for creasing blanksof different widths and sizes. The bar 10 is formed with a hollow 11,extending longitudinally through it, said hollow having a contractedportion or neck 12 opening at the front face of the bar and alsoextending along the entire length thereof, so as to form in said bar, inconnection with the hollow 11, a longitudinal slot of T shape incross-section.

13 indicates the drivin g-shaft of the machine, journaled on the sidepieces 1 of the frame to extend transversely thereof below thefeed-table 2 and carrying at one end, as shown in Fig. 3, tight andloose pulleys l-l, by means of which the machine may be operated from adriving-belt. (Not shown.) On the shaft 13, between the frame-uprights,are carried the lower creasing devices in the form of disks or rolls 15,having keys 16 arranged for engagement with a keyway or groove 17,extendinglengthwise of the shaft 13, between the frame-uprights. By thisconstruction it will be seen that the lower creasing devices 15 are heldto turn with the driving-shaft 13, while bein g capable of adjustmentlengthwise along the same toward or away from each other to permit ofcreasing blanks for differerently sized or proportioned boxes. The shaft13 is also provided outside the frame with a pulley, over which extendsa driving belt or band 18, which is carried up, as shown in Figs. 1 and3, over a pulley 19 on a shaft 20,extending transversely across themachineframe above the guide-bar 10, being journaled at its ends inbrackets secured to the uprights l, as shown in Fig. 3, and providedwith a longitudinal keyway or groove 21, extending along its lengthbetween said uprights. 0n the shaft 2U are mounted bevelgears 22,arranged in pairs or sets connected by sleeves 23 and having keys toengage the keyway or groove 21 in the shaft, so that the pairs or setsof gears 22 are held to turn on the shaft, but are capable of adjustmentalong the same in a manner and fora purpose similar to thebefore-mentioned lower creasing devices or disks 15 on the driving-shaft13.

As shown, the gears 22 of each set or pair have their driving-facesoppositely arranged for driving engagement with bevel-gears 24, held onthe upper ends of vertical shafts 25, arranged in the same verticalplane with shafts 2O and 13, but extending at right angles thereto onopposite sides of the gears 22, said vertical shafts 25 being held incollars or journals 26, formed at top and bottom of the front face of anadjustable carrier 27, made, as shown in Figs. 4 and 6, in the form of arectangular metal plate.

the shafts 25 carry the upper creasing devices 28, made in the form ofdisks or flattened The lower ends of rolls mounted to turn on a verticalaxis at opposite sides, respectively, of one of the lower creasingdevices or disks 15 of shaft 13.

Each carrier 27, as shown in Fig. 3, carries the two shafts 25, drivenfrom one set or pair of the gears 22, together with the upper creasingdevices or disks 28, which operate, as will be hereinafter explained, inconnection with one of the lower creasing devices or disks 15, and eachof said carriers :is formed on its back face with a vertical rib 29,adapted to fit and slide in a channel 30, formed vertically in the frontface of a slide-plate 31. (Shown in detail in Figs. 5 and 7, the channel30 being indicated in dotted lines in said figures.) The arrangement ofthese parts is shown in Fig. 2, which is a cross-section through saidriband channel. The rear face of the slide-plate 31 is also formed witha rib 32, formed to extend transversely of the machine or at rightangles to the rib 29 and channel 30 and adapted to enter the reducedportion or neck l2 of the T-slot in the guidebar 10, so as to hold theslide-plate 31 on said bar and guide it for movement longitudinallyalong the same.

The carrier 27 is formed with a vertical slot 33 extending through it,as shown in Fig. i, at the central part of the rib 29, and theslideplate 31, as seen in Fig. 5, is formed with a perforation 34 at thecenter of the rib 32, these openings serving for the passage of a bolt35, having a head or enlargement 36, mounted in the enlarged portion orhollow 11 of the T-slot of bar 10, the shank of the bolt extending outthrough the neck 12 of said -slot, as shown in Fig. 2, through theopenings 34 and 33 in the slide-plate and carrier, when the ribs ofthese parts are properly engaged with the channel 30 and said T-slot,and carrying a washer 37 and nut 38 outside of said carrier, as shown inFigs. 2 and 3, so that when the parts are properly adjusted the IIO nutmay be tightened to hold them against displacement. The slide plate 31is also formed at its upper edge with a central lug 39, which projectsupward and forwardly over the carrier 27 and is provided with a screw40, the tip of which engages with the carrier 27 and is adapted for usein adjusting the carrier vertically to raise and lower the uppercreasing disks or devices 28, the rib 29 moving when the carrier isadjusted lengthwise in its channel 30. By this construction it will beseen that when the nut 38 is unscrewed the carrier 27 may be adjustedvertically by means of the screw 40, so as to move the upper creasingdevices nearer to or farther away from the lower creasing devices 15 tosuit stock of different thicknesses, or the slide-plate, together withthe carrier and parts carried thereby, may be adj usted transversely orlaterally of the machine, the rib 32 of the slide-plate moving along theslot of the guide-bar lO, so as to bring the creasing mechanisms atopposite sides of the machine nearer together or farther apart toaccommodate the machine for use in creasing blanks for differently sizedor proportioned boxes.

As shown in the drawings, the periphery of each of the lowercreasing-disks 15 is .formed with a central rib or swelled part 15a,extending around it and adapted to project up between the correspondingpair of upper creasing-disks 28, which are provided on their under sideswith circular central projecting parts 28C, having rounded edges 28a, asshown in Fig. 9, and forming at the lower side of each disk an annularflat face or shoulder 28b to engage the top surface of the stock, beingcreased at points over the central rib or swelled part 15 of thecorresponding lower disk 15. The projecting parts 28c of the disks 28also engage the upper surface of the stock at points over the peripheryof the lower disk 15, so that when the stock is fed tothe creasingdevices from the feed-table 2, which is arranged, as shown in Figs. 1and 2, at a level with the bite of the disks, the lower surface of thestock will be engaged and forcedupward-at the creasing-line by theperipheral rib or swell 15a of the lower disk 15. The rib or swell 15 isformed with a flat or nearly iiat outer face, and at its sides therounded edges 28CL of the projecting parts 28C of the u pper disks 28will engage the uppersurface of the stock to form downward bends on eachside of said creasing-line, so that a wide crease is formed in thestock.

Owing to the arrangement of the lower creasing-disk 15 with itsperipheral rib or swell projecting between the upper disks 28 it will beseen that whenthe'corresponding slide-plate 31 is adjusted transverselyof the machine the lower creasing-disk 15 will also be movedtransversely of the machine along its shaft 13, on which it is held toturn, but capable of free endwise movement, and by reason of thearrangement of the gears 24 at the upper ends of shafts 25 outside oftheir intermeshing driving-gears 22 the saidgears 22 will also be causedto be moved along the shaft 2O simultaneously with the adjustment of theslide-plate 'and carrier. In this way the machine is made much moreconvenient for use, since but a single adjustment is required for eachset of creasing mechanism and their driving devices. Y

On one end of the driving-shaft 13 is carried a pulley, over whichpasses a belt or band 41, extending up over a pulley on a shaft 42,journaled transversely across the frame at the rear of the creasingmechanisms and geared, by means of gears 43 or otherwise, to a similartransverse shaft 44, arranged above it and in the same vertical plane.On the lower shaft 42 are mounted rolls 45, having keys engaging keywaysor grooves extending lengthwise in the shaft 42, so as to hold saidrolls to turn with the shaft, while permitting them to be adjustedlengthwise therealong, set-collars 47 or equivalent devices beingprovided for holding the rolls against movement endwise on the shaftwhen in adjusted position. Circular or disk-like cutters 48 are held onthe upper shaft 44 alined with the centers of the rolls 45, which rollsare provided with centrally arranged peripheral grooves 46, as shown inFigs. 3 and 8, to receive the cutting edges. On opposite sides of thecutters 48 are mounted rolls 49, which, together with the cutters, havekeys to engage a keyway or groove extending lengthwise in the shaft 44,so that the cutters 48 and rolls 49 are held to turn with said shaft,while being capable of adjustment along the same. Set-collars 50 arealso provided onopposite sides of the respective pairs of rolls 49 topermit of securing said cutters and rolls against movement along theshaft when in adjusted position. The rolls 49 are adapted to press uponthe stock passing between them and the lower rolls 45, so as to securelyhold said stock against lateral movement while being operated upon bythe cutters 48. By this means it will be seen that the cutters operateto trim the edges of the stock after the creasing devices have operated,so that at a single passage through the machine the stock is creased andtrimmed along two of its edges. To crease and trim the other edges 0fthe stock, the operation will be repeated.

In order to prevent the edges of the blanks from bending or curling upin front of the creasing devices when gripped thereby, I prefer toprovide guards 51, formed of bent metal strips slotted for the passageof the bolts 35 and held adj ustably thereon by the nuts 38. The stripsare bent at their lower ends 52 to extend out in front of the disks 28in position to engage the upper surfaces of the blanks fed to thecreasing mechanisms.

In operation the blanks are fed from the feed-table 2 between the upperand lower creasing devices, the movement of all said devices imparted bythe positive driving mechanism thereof acting to draw the stock throughthe machine. Said devices being arranged in sets each comprising onelower and two upper creasing-disks and these sets being capable of readyadjustment toward and from each other, it is evident the machine is madeespecially well adapted for use. After having been properly creased theblanks are operated upon by the cutters, which serve to trim them downto the desired size, and after passing through the machine the creasedand trimmed blanks fall upon the deliverytable 4 and by engagement withthe stop 5 thereof are straightened, so as to form a uniform pile onsaid table.

From the above description it will be seen that the improvedcreasing-machine is of an extremely simple and compact construction andis especially well adapted for use, owing to its ready adj ustability toaccommodate different sizes and forms of boxes and different grades ofmaterial, and it will also be apparent from the above description thatthe device is capable of some modification without material departurefrom the principles and IOO IIO

spirit of the invention, and for this reason I do not wish to beunderstood as limiting myself to the precise form and arrangement of theseveral parts herein set forth.

I-Iaving thus described my invention, I claim- 1. In a creasing-machine,the combination of a frame, a creasing device formed with cylindricalend portions and a central projecting peripheral rib between saidcylindrical end portions adapted for engagement with one face of thestock, means for driving said creasing device to draw the stock throughthe machine, and two creasing devices arranged for engagement with theother face of the stock at opposite sides of the peripheral rib of thefirst-mentioned device and adapted to bend the stock over the oppositesides of said rib, substantially as set forth.
